Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor joint device in which when a joint portion becomes narrow due to an earthquake or the like, a tip portion of a joint plate covering the floor joint portion protrudes onto one floor frame to absorb the shaking motion.
[0002]
[Prior art]
Conventionally, this type of floor joint device includes a joint plate support guide concave portion having an inclined joint surface formed on the floor housing on one joint portion side of the floor housing of the left and right buildings provided via the joint portion. The upper side of the other side frame of the left and right floor frame is substantially flush with the upper surface of the other floor frame, the rear end is attached to be movable upward, and the front end is the joint plate support guide. The joint is configured by a joint plate that covers the concave portion and that, when the joint portion becomes narrower, the tip portion can ride on one floor frame.
[0003]
[Problems to be solved by the invention]
In a conventional floor joint device, the rear end of the joint plate does not move upward unless the center of gravity of the joint plate passes through the support part of one floor case, and the tip of the joint plate is one floor case. There is a disadvantage that a large gap is generated by projecting upward, resulting in a danger, and when the load is applied on the rear end portion of the joint plate that has moved upward, it moves downward and is dangerous. It was.
[0004]
In view of the above-described conventional drawbacks, the present invention automatically pushes the rear end portion of the joint plate upward when the joint portion is narrowed so that the joint plate is inclined, and the tip portion of the joint plate is moved to one side. Provided is a floor joint device that can be used safely without being moved downward even when a load is applied to the rear end of the joint plate that has been pushed up while preventing it from projecting greatly onto the floor frame. The purpose is that.
[0005]
The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a joint plate support guide concave portion having a sloped anti-joint portion formed on one joint portion side of the left and right floor rods provided via the joint portion, A joint plate support member fixed to the other joint section side floor casing of the left and right floor casings, and an inclined sleeper whose upper surface fixed to the joint plate support member is sequentially located above the center portion of the joint section; The round pipe material supported by this sleeper is fixed to the bottom surface of the rear end portion, the upper surface is substantially flush with the upper surface of the other floor frame, the front end portion covers the joint plate support guide recess, and the joint portion is narrow Then, the joint plate that rides on the one floor frame and the rear end portion of the joint plate is inserted into the round pipe member attached to the joint plate support member so as to be movable by a predetermined amount. Support pin Constitute a floor joint device and the holder having.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
[0008]
In the first embodiment of the present invention shown in FIGS. 1 to 7, reference numeral 1 denotes a joint between left and right buildings 3, 3 provided through a joint portion 2 and floor frames 3a, 3a such as buildings and walls. The floor joint device 1 according to the present invention covers the section, and the floor joint device 1 is formed on the floor housing 3a on one joint portion side of the left and right floor housings 3a, 3a. Plate support guide recess 5, angle joint plate support member 7 fixed to the other joint portion side floor housing 3a of the left and right floor housings 3a, 3a by a plurality of screws 6 and the like, and this joint plate support member 7 is a sleeper 9 of an inclined surface 8 in which the center side of the joint portion is sequentially positioned upward, and a round pipe member 10 supported by the sleeper 9 is fixed to the bottom surface of the rear end by welding or the like, The top surface is substantially flush with the top surface of the other floor case 3a, When the joint portion 2 covers the joint plate support guide recess 5 and the joint portion 2 becomes narrower, the joint plate 11 rides on the one floor frame 3a, and the rear end portion of the joint plate 11 attached to the joint plate support member 7 A holding tool 13 having a support pin 12 inserted into the round pipe member 10 and a pivot pin 14 at the upper part of the rear end and the tip of the joint plate 11, 14 and end guide plates 15, 15 pivoted at 14.
[0009]
As shown in FIGS. 3 and 4, the joint plate 11 is formed of a metal plate or the like in a thin square dish shape, and is attached to the joint plate body 16 via a mortar, concrete 17 or the like. , And a flooring 18 such as a tile and a floor decorative board.
[0010]
As shown in FIG. 5, the holder 13 includes a pair of L-shaped holder main bodies 19 and 19 fixed by a plurality of screws 6 or the like at portions near both ends of the joint plate support member 7. The support pins 12 are inserted into the shaft holes 20, 20 formed in the portions near the upper portions of the holder main bodies 19, 19, and are inserted into the round pipe member 10, and are attached to both ends of the support pins 12. And retaining devices 21 and 21 such as pins and nuts.
[0011]
When the floor joint device 1 configured as described above is swung so as to widen the joint portion 2 due to an earthquake or the like, the tip of the joint plate 11 slides on the joint plate support guide concave portion 5 as shown in FIG. To absorb the shaking movement.
[0012]
When the joint portion 12 is swung so as to become narrow, the tip end portion of the joint plate 11 slides upward along the inclined surface 4 on the side opposite to the joint portion of the joint plate support guide concave portion 5 as shown in FIG. At the same time, the corner of the other floor frame 3a serves as a fulcrum for the rear end, and the round pipe member 10 moves on the sleepers 9 of the inclined surface 8 and moves the rear end of the joint plate 11 upward.
For this reason, it is prevented that the front-end | tip part of the joint plate 11 protrudes largely on one floor frame 3a, and it can be used safely.
[0013]
